A method, a computer program product, and a system for determining an optical parameter of an optical lens as well as a related method for producing the optical lens by adjusting the optical parameter are disclosed. The method includes: capturing an image picturing the optical lens by using a camera; and determining an optical parameter of the optical lens by processing the image, wherein the camera generates a signal related to a position of a focus, and the optical parameter of the optical lens is determined by using the signal related to the position of focus. The method and the system allow determining the optical parameter of the optical lens in a direct fashion by applying the signal related to the position of the focus as generated by the camera as a measured value for the optical parameter of the optical lens.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method according to claim 1, wherein the position of the focus is adjusted by at least one of the camera or a user.
3. The method according to claim 1, wherein the at least one signal related to the position of the focus serves as an input for at least one calibration function, which is used in determining the at least one optical parameter of the at least one spectacle lens.
4. The method according to claim 1, wherein the at least one further image is captured by further using the at least one camera, or wherein the at least one further image is a comparison image.
5. The method according to claim 1, wherein the at least one focus of the at least one camera is adjusted to at least one object in space in at least one first distance to the at least one spectacle lens and in at least one second distance to the at least one camera, wherein the at least one optical parameter of at least one spectacle lens is determined by processing the at least one image further capturing the at least one object in space in the at least one first distance to the at least one spectacle lens and in the at least one second distance to the at least one camera.
6. The method according to claim 5, wherein the at least one object is or comprises at least one eye of the user.
12. The system according to claim 11, wherein the at least one camera is configured to adjust the position of the focus by using at least one of an autofocus system or an autofocus function as comprised by the at least one camera, or an input generated by the user.
14. The system according to claim 11, wherein at least one of the at least one camera or the at least one evaluation unit is comprised by a mobile communication device, wherein the at least one camera configured to capture the at least one image is at least one of a rear camera or a front camera as comprised by the mobile communication device.
